The Union Cycliste International (UCI) is the world governing body of cycling as a sport encompassing road racing, track and mountain bike, cyclo-cross, BMX, trials, paracycling and indoor cycling. Founded in Paris in 1900 the organisation is now based in Aigle, Switzerland and is recognised by the IOC (International Olympic Committee). The current president is Frenchman, David Lappartient.
The UCI sets the regulations for the competitive aspects of the sport of cycling and oversees the enforcement of them from racing to anti-doping (the UCI is signed up the the WADA code) and equipment. All the rules can be downloaded from the UCI's website.
UCI world championships are held annually in each of the disciplines as well as World Cups (excluding men's road racing, but including women's). Road, track, mountain bike and BMX are the four cycling disciplines included in the Olympic programme.
